I'm seeing a very high CPU from pigz when the backup process is running:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
22280 root 39 19 11808 1268 560 R 94.4 0.0 346:57.55 pigz
15894 root 39 19 507m 413m 4352 S 17.9 1.3 50:12.94 pkgacct - allan
Its a large account, around 50Gb, so I'm not suprised that it will take a while to zip up, although the amount of time in the process is very concerning 50 hours for pkgacct and 348 hours for pigz...
What is concerning me most is the impact this is having on the web server. The load average is:
load average: 3.44, 2.39, 2.26
but even when its been down around 1, the load time has been exceptionally slow.
What can I do to improve this - both the zip time and more importantly keeping the server performant during the backup?
Thanks,
Allan
